Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a self-cleaning screen plate of a vibrating screen. Background Art

[0002] The vibrating screen works by utilizing the reciprocating vibration generated by the excitation of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar gyratory vibration, while the lower rotating weight causes the screen surface to produce conical gyratory vibration. The combined effect causes the screen surface to produce compound gyratory vibration. Its vibration trajectory is a complex spatial curve, which is projected as a circle on the horizontal plane and an ellipse on the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating weights, while the curve shape of the motion trajectory of the screen surface and the motion trajectory of the material on the screen surface can be changed by adjusting the spatial phase angle of the upper and lower weights. During the screening process, the material is easily stuck in the screen hole, and the material in the screen hole can be removed by vibration to ensure the smoothness of the subsequent screening operation.

[0003] A Chinese patent discloses a self-cleaning screen plate of a vibrating screen (Announcement No. CN103182381A). The patent technology has a reasonable structure, and the self-cleaning effect of the screen plate of the vibrating screen is good. It can effectively improve the screening efficiency of the vibrating screen and reduce the labor intensity of workers. However, the installation angle of the self-cleaning screen plate of the vibrating screen needs to be determined according to the installation position. The position angle is fixed after installation, which affects the flexibility of use. The self-cleaning is completed by shaking off the material on the screen plate through the vibration bar at the fixed position. This method increases the overall thickness of the screen plate, which is easy to retain materials and is not conducive to screening efficiency. Therefore, those skilled in the art provide a self-cleaning screen plate of a vibrating screen to solve the problems raised in the above background technology. Utility Model Content
